Volume II section 3 clause no. 12.2.2 As per the referred clause 220/66/11kV,150 MVA

transformer first unit needs to undergo dynamic short

circuit withstand test.

It is to be noted that it will be difficult to conduct short

circuit withstand test on 220/66/11kV,150 MVA

transformer in India with the existing facilities. If at all it is

arranged in CPRI, it will take almost 8-9 months to

complete the test. And if is not possible in CPRI then for

conducting the SC test, the manufactured unit has to

go to KEEMA, which takes a minimum period of 12-18

months and sometimes KEMA does not provide any

confirmation on dates due to their loading on test

facility. Project duration being 12 months (lot 1) & 18

months (lot 2),it is impossible to conduct the dynamic

short circuit withstand test.

Keeping the above point in view, request you to kindly

delete the clause pertaining to dynamic short circuit

test that needs to be conducted on the first unit of

transformer.

Conducting dynamic short circuit

withstand test can be considered

for waiver subject to condition

that the design provided by the

bidder shall be got approved by

competent agency.

Bidder who posses Similar/Higher

rating SC report, within the last 5

Years, need not conduct SC

again. However, the design
